- Simplified null/empty checks across TypeScript codebase using optional chaining operator (?.) for improved readability.
- Replaced explicit null checks in validation logic with optional chaining in oauth-discovery, gemini-cli, claude, zai, and lsp modules.
- Updated error handling in Rust command invocation to use double question mark operator (??) for cmd_result.
- Consolidated null validation patterns across tools (bash-skill-urls, browser, gemini-image, resolve) and keybindings using optional chaining.
The grep, ast_grep, and ast_edit renderers used group-count-based
collapse that always included the first group unconditionally,
allowing collapsed output to remain visually large when a single
group contained many lines.
Add maxCollapsedLines to renderTreeList that enforces a strict
total-line cap in collapsed mode. Items that exceed the remaining
budget are skipped entirely (no broken fragments). The isLast tree
branch is computed after the budget check to avoid double-last
branches when a summary line follows.
Remove the per-tool getCollapsedMatchLimit / getCollapsedChangeLimit
helpers that are now redundant.
Fixes#455
Made-with: Cursor
- Added contract system for validating benchmark commands, metrics, scope paths, constraints, and off-limits paths.
- Contract validation enforces matching initialization parameters against autoresearch.md before init_experiment.
- Segment fingerprinting detects configuration drift and warns when metrics are not directly comparable.
- Added pending run detection and recovery to resume incomplete experiments from .autoresearch/runs/.
- Run directories organize artifacts with benchmark logs and optional checks logs for traceability.
- Extended experiment state to track run number, command, scope, off-limits, constraints, and fingerprint.
- Restructured hashline edit schema from flat op/pos/end/lines fields to nested loc/content objects with discriminated union types.
- Replaced operation names (replace_line, replace_range, append_at, prepend_at) with unified loc object patterns supporting line, block, append, and prepend anchors.
- Updated content field to accept array of strings or null instead of lines parameter in edit entries.
- Refactored edit resolution logic to dispatch on loc shape instead of op enum, simplifying location handling.
- Added boundary duplication warning to detect off-by-one range errors in replace_range and replace_line operations.
- Updated hashline tool documentation with boundary duplication trap guidance to prevent closing delimiter duplication.
- Added git branch isolation for autoresearch sessions with automatic branch creation, reuse, and worktree safety checks.
- Added scope definition sections (Files in Scope, Off Limits, Constraints) to autoresearch template for explicit session boundaries.
- Added keybinding matcher utilities for consistent escape/cancel key handling across interactive components.
- Added ASI metadata validation (hypothesis and rollback context) in log_experiment tool for experiment tracking.
- Refactored keybinding logic across 13 components to use centralized matcher functions instead of inline key checks.
- Renamed hashline operation types for clarity: append->append_at, prepend->prepend_at, append_eof->append_file, prepend_bof->prepend_file.
- Updated all operation type references in patch implementation, tests, and documentation to reflect new naming convention.
- Restructured hashline tool documentation with hierarchical sections and simplified examples for improved clarity.
- Consolidated validation rules and added explicit warning about invalid anchors and operation/field combinations.
- Added `defaultInactive` property to ToolDefinition for conditional tool registration and activation control.
- Added dynamic tool activation/deactivation API `setActiveTools()` for managing experiment tools in autoresearch mode.
- Replaced single `command-start.md` workflow with separate `command-initialize.md` and `command-resume.md` prompts for autoresearch initialization and session resumption.
- Added interactive intent dialog for autoresearch optimization goals with automatic session resumption detection based on autoresearch.md presence.
- Refactored autoresearch command handler to distinguish resume vs initialize flows and dynamically activate/deactivate experiment tools based on mode and session state.
- Added retry mechanism for benchmark tasks with separate system and retry prompt templates to improve edit success rates.
- Introduced autocorrect tracking metrics including autocorrect-free success rate and edit autocorrect counts in task and benchmark summaries.
- Refactored prompt building into modular functions (buildBenchmarkSystemPrompt, buildInitialBenchmarkPrompt, buildRetryBenchmarkPrompt) with BenchmarkPromptDelivery type for distinguishing initial and follow-up messages.
- Added session management with cache-keyed provider session IDs using xxHash64 and centralized RPC argument building via prepareBenchmarkSessionSetup.
- Refactored hashline edit operations from implicit `replace` to explicit `replace_line` and `replace_range` with mandatory `end` parameter for ranges.
- Added file-level operations `append_eof` and `prepend_bof` for boundary insertions, making `pos` required for anchor-based operations.
- Enforced stricter anchor validation per operation type and simplified edit application logic by separating file-level from anchor-based operations.
- Updated hashline edit application to preserve duplicated boundary lines without auto-correction, changing previous behavior.
- Added autoresearch extension with autonomous experiment loop supporting init, run, and log experiment tools for metric-driven optimization.
- Added widget placement system enabling extensions to position UI components above or below the editor via ExtensionWidgetOptions.
- Added dashboard controller with interactive overlay for viewing experiment results, metrics, and progress with keyboard navigation.
- Removed auto-correction logic for off-by-one range edits in hashline editor to preserve user intent in patch operations.
- Added state reconstruction utilities to parse autoresearch.jsonl logs and rebuild experiment state across sessions.
- Added comprehensive type definitions and helper utilities for metric parsing, ASI validation, and process management.
- Changed bash interceptor configuration from boolean flags to customizable pattern-based rules array.
- Clarified hashline range replace semantics: end parameter is now strictly exclusive boundary.
- Fixed bash interceptor to apply built-in default rules when no custom patterns are configured.
- Updated hashline range validation and calculations to enforce exclusive end semantics throughout.
- Added renderInlineMarkdown() utility function to support inline markdown rendering with optional base color styling.
- Refactored ask tool to render questions and option labels with markdown formatting for improved text styling.
- Updated hook-input and hook-selector components to render titles as markdown with theme-aware styling.
- Implemented recursive token processing for nested markdown elements including bold, italic, code, links, and strikethrough.
Fixes#491
- Fixed rate-limit-utils to recognize and classify 'usage limit' errors as QUOTA_EXHAUSTED instead of transient.
- Added isUsageLimitError() utility function for unified detection of persistent quota limit errors across providers.
- Fixed Codex provider to return immediately on usage-limit errors instead of retrying, preventing unnecessary 5-minute delays.
- Removed usage.?limit pattern from TRANSIENT_MESSAGE_PATTERN to prevent misclassification of persistent quota errors.
- Added ACP (Agent Client Protocol) mode for headless agent operation via --mode acp flag.
- Integrated Agent Client Protocol SDK with session management, streaming communication, and event mapping.
- Added ensureOnDisk() method to SessionManager for immediate session persistence without requiring assistant messages.
- Changed session persistence to use atomic file rewrite for unflushed sessions.
- Implemented AcpAgent class with session management, prompt handling, MCP server configuration, and event streaming.
- Restructured model policy application logic to improve readability and reduce nesting.
- Extracted model override application into dedicated function calls for consistency.
